Pros

Financially secure organization with significant resources in the past.

Cons

The commercial (Human Health) organization expanded faster than the actual business needs. Leadership seemed focused on headcount growth, but roles were not always structured with clear responsibilities. As a result, many talented people ended up underutilized and found limited opportunities for meaningful development
